From 863c1fd9814618eefba02218f8fadf8a430c2a17 Mon Sep 17 00:00:00 2001 From: Soheil Hassas Yeganeh Date: Wed, 27 Apr 2016 23:39:00 -0400 Subject: [PATCH] tcp: remove an unnecessary check in tcp_tx_timestamp Remove the redundant check for sk->sk_tsflags in tcp_tx_timestamp. tcp_tx_timestamp() receives the tsflags as a parameter. As a result the "sk->sk_tsflags || tsflags" is redundant, since tsflags already includes sk->sk_tsflags plus overrides from control messages.
